o NTFS is considered a 64-bit filesystem that allows for large volumes and very
large file sizes
o NTFS has a lot of key features such as journaling, snapshots, security, POSIX
compliance, indexing, and dynamic discsJournaling allows forfaster recovery
from power outages and crashes
o Snapshots allow you to make a read-only copy of a file, even if it is already
locked
o NTFS has a higher security level and allows you access to audit trails, quota
management, and an encrypting filesystem
o Each file can be protected against unauthorized access
o POSIX supports Unix and Linux compatibility between NTFS and a Unix or Linux
filesystem
o Windows and NTFS are not case sensitive
o JASON and jason would be the same file to NTFS
o Windows doesn't rely on case sensitivity when reading NTFS but Linux and Unix
will
o Indexing is a catalog of file and folder locations to help speed up searches
o Dynamic discs can combine physical discs into one larger disc that is understood
by the operating system
2. File allocation table 32, also known as FAT32
o You can only have a total drive size of up to 2 TB and the maximum file size is 4
GB
o FAT is limited due to it being a 32-bit allocation table, where the maximum file
size is around 4.2 billion bytes or 4 GB
o FAT is supported by Windows, Unix, Linux, and macOS
o FAT32 is usually used on removable drives like external hard drives or USB flash
drives
3. Extended file type system, also known as ext3 and ext4
o These are supported by Linux and Unix systems, but not by Windows or macOS
by default
o ext3 has a maximum volume size of 32 TB and maximum file size of 2 TB
o ext4 has a maximum volume size of 1 EB and maximum file size of 16 TB
